Bricks are one of the oldest building materials and have been used for thousands of years. They remain a popular choice in construction today due to their versatility, durability and aesthetics. There are different types of bricks, each with unique properties and uses. In this article we examine the types of bricks most used in construction.
We have discussed around 20 types of bricks under different categories or classifications in this article.
Classification based on materials
1. Bricks
Valued for their timeless beauty and durability, clay bricks have been a building staple for centuries. These bricks are made from natural clay that is molded, dried and fired in kilns to achieve the desired strength and texture.
Available in a variety of colors from earthy reds to soft browns, clay tiles add warmth and character to buildings. Clay tiles provide excellent thermal insulation, help regulate internal temperatures and reduce energy costs.
Furthermore, its porous nature allows efficient absorption of moisture, preventing the formation of damp and mold. When well cared for, clay tiles can stand the test of time, making them a preferred choice for traditional and contemporary architectural projects.
2. Concrete blocks
Concrete blocks are made from a mixture of cement, sand and aggregates and provide unmatched strength and durability.
Unlike mud bricks, which are made from natural clay deposits, concrete bricks can be made from locally available materials, reducing transport costs and environmental impact. These bricks are formed by pouring concrete mix into molds and curing under controlled conditions to achieve ideal strength and consistency.
Concrete blocks come in various shapes and sizes, including solid, hollow, and interlocking designs , and offer versatility in construction projects. They are valued for their ability to withstand harsh weather conditions, making them ideal for outdoor applications such as retaining walls, paving and landscaping.
3. Sand-lime bricks
Sand-lime bricks, also called calcium silicate bricks, are made by mixing sand, lime and water, followed by a chemical reaction called hydration.
This process creates calcium silicate hydrate, which binds the components together to create dense, uniform bricks. Sand-lime bricks offer exceptional strength, durability and dimensional stability, making them suitable for structural structures and industrial applications.
These bricks have a smooth texture and uniform appearance, making them ideal for architectural surfaces and decorative elements. Furthermore, sand-lime bricks have excellent fire resistance properties, ensuring structural integrity and safety in fire-prone environments.
4. Fly ash bricks
